A particle is projected at an angle of elevation `alpha` and after t second it appears to have an elevation of `beta` as seen from the point of projection. Find the initial velocity of projection A particle is projected at an angle of elevation `alpha` and after t second it appears to have an elevation [...]

A hose lying on the ground shoots a stream of water upward at an angle of 60∘ to the horizontal with the velocity of 16 m/s. The height at which the water strikes the wall 8m away is A hose lying on the ground shoots a stream of water upward at an angle of 60∘ [...]

Choose the correct option Two seconds after the projection, a projectile is moving at 30∘ above the horizontal, after one more second it moves horizontally (g=10 m/s 2). a projectile is moving at 30∘ above the horizontal after one more second it moves horizontally (g=10 m/s 2). Choose the correct option Two seconds after the [...]

An aeroplane is flying horizontally with a velocity `720 km/h` at a height of `2000 m`. When it is vertically at a point `A` on the ground, a bomb is released from it. The bomb strikes the ground at point `B`. The distance `AB` is a bomb is released from it. The bomb strikes the [...]
